Recent Outages - Technical Side of it

My current internet is with Telstra Bigpond on Cable one terabyte a month. Lately there have been a lot of dropouts on the broadcast due to some unknown network fault on the internet side.

So what happened? It seems like from a network engineers point of view, that one of the core routers was malfunctioning. All the evidence certainly pointed to it. While my internet speed was more than enough bandwidth wise:

As you can see, this is fast enough to run many streams side by side however the speed was never the problem. It was more the packet loss, latency and jitter:

During the outages, I was getting a consistent F Grade which would drop the network connection every 10 minutes. Jitter was usually pretty bad too. Just look at this:

While the jitter is not that bad in this image above, it could be better. The jitter I was getting was 20+ which is catastrophic for all types of streams.
